* \brief Implements a generic object factory.
*
* <i>The Factory Method pattern is an object-oriented design pattern.
* Like other creational patterns, it deals with the problem of creating objects
* (products) without specifying the exact class of object that will be created.
* Factory Method, one of the patterns from the Design Patterns book, handles
* this problem by defining a separate method for creating the objects, which
* subclasses can then override to specify the derived type of product that will
* be created.
* <br>
* More generally, the term Factory Method is often used to refer to any method
* whose main purpose is creation of objects.</i>
* <div ALIGN="RIGHT"><a href="http://en.wikipedia.org/wiki/Factory_method_pattern">
* Wikipedia</a></div>
*
* Loki proposes a generic version of the Factory. Here is a typical use.<br>
* <code><br>
* 1. Factory< AbstractProduct, int > aFactory;<br>
* 2. aFactory.Register( 1, createProductNull );<br>
* 3. aFactory.CreateObject( 1 ); <br>
* </code><br>
* <br>
* - 1. The declaration<br>
* You want a Factory that produces AbstractProduct.<br>
* The client will refer to a creation method through an int.<br>
* - 2.The registration<br>
* The code that will contribute to the Factory will now need to declare its
* ProductCreator by registering them into the Factory.<br>
* A ProductCreator is a just a function that will return the right object. ie <br>
* <code>
* Product* createProductNull()<br>
* {<br>
* return new Product<br>
* }<br>
* </code><br>
* - 3. The use<br>
* Now the client can create object by calling the Factory's CreateObject method
* with the right identifier. If the ProductCreator were to have arguments
* (<i>ie :Product* createProductParm( int a, int b )</i>)
